Open Close Pro Hook

Hi there,

I use the pro plugin and I need to know what hook can I use to show or hide a class?

For example right now I have a piece of JS+PHP code that check if it’s between X and Y hours and it will trigger the code.
My goal is to get automatically this information via Open Hours to avoid having to recode this each time I change my shop hours.

if(current_time('H:i') >= '11:30' && current_time('H:i') <= '22:33'){
	echo "<script type=\"text/javascript\">var d = new Date(); var dayOfWeek = d.getDay();
		if(dayOfWeek >= 0 && dayOfWeek <= 6) { 
		var x = document.getElementsByClassName('progress');
		var i;
			for (i = 0; i < x.length; i++) {
				x[i].style.display = 'block';
			} 
		}
	</script>";
}

Thank you!
